Brief background: Quite a while back, I made brief use of the old Opethfeldt 7 ENB, because I had been hoping to find an ENB that gave a realistic look - specifically, nice and bright when the sun is supposedly shining on things. Opethfeldt was just about the only public ENB that even seemed to be trying. (Since then, Kakasi ENB and "Unreal" ENB have done a rather better job, but neither will ever be made public.) Here is a screenshot I took at the time because I was particularly impressed with what it had accomplished:

Image

Opethfeldt always had a dealbreaker flaw, however: Almost uniquely among all ENBs I ever saw, it made the entire screen look washed-out. This was not due to bloom; turning bloom off did not fix it. It was not due to the lensmask; turning that off did not fix it. It was something I was never able to determine - perhaps it was actually important to how Opethfeldt managed to look sunny.

Enter Dovah Nakiin ENB. It's an ENB that specifically tries to reproduce the look of "Unreal" ENB. And it does a fair job of it. Overhead sunlight outdoors is without question bright. But there are problems:

1. No adaptation at all - which I sort of fixed.

2. No bloom at all, not even in the brightest scenarios, which is just not going to work. Brightly reflective spots need some bloom to be convincing. Here is where my lack of expertise becomes a problem. In the "Bloom" list, there is a setting called "Ignore Weather System". In this ENB, this item is not checked. Checking it gives two results: Bloom gets properly enabled, and the visuals change, presumably in that a lot of the things the ENB tries to set up are suddenly being ignored, defeating the purpose of the ENB. So it seems I have a choice here: Let the ENB do what it was set up to do, or have bloom. This one has me stumped.

3. Nights are too bright. I'll have to deal with this eventually.

4. Interiors aren't bright in spots where sunbeams are shining in, as revealed by this recent screenshot where I went back to the same spot as in the earlier shot:

Image

Compared to how Opethfeldt represented interior sunlight, the above result is deflating. I intend to correct that. But, for starters, without bloom, that will be impossible. I also have not had a lot of luck tweaking the Dovah Nakiin's settings to reproduce Opethfeldt. Dovah Nakiin makes heavy use of extra (I assume) SweetFX settings, and those seem to be the only settings I can tweak to effect a change in interior brightness / contrast. I have not been able to net a decent-looking result, let alone reproduce Opethfeldt's look, and I feel it's pointless to begin until I have Bloom working. Far as I can tell, Opethfeldt uses almost no "extra" settings at all, and that probably explains at least some of my difficulty.

If anyone wants to take a stab at this, or offer some settings or suggestions, I'm all ears. Thanks in advance.

There are too many variables and code parts which modify what you marked on screenshots and even if you find preset you like, different weather will make shit from it, so first of all you must test for only certain weather type or use weather system of presets, if they have it (single weather as basis is sunny day preffered by me). In general, ambient light is what in shadows. Direct light is sun. But tonemapping and other color processing code in enbeffect.fx (check parameters there too) compress color space and you may not see contrast even if it's really big. There is no single recommendation regarding such things.

PS: i'm working on new version which will have variables which replace game weathers instead of just tweak them, so will be simpler to modify and to not depend from weathers.

Probably correct about the weathers. I guess what I'm hoping to do is produce the Opethfeldt result pictured above within the Dovah Nakiin ENB during a clear day inside, and then go from there. The extremely frustrating thing is that I haven't really even gotten close. I've gotten brighter results than what the ENB starts out as, but those super-sharp boundaries between sunlit and not-sunlit (on the ground and on the clothes) absolutely elude me. And so does the way the clothes in sunlight looks nice and bright while the clothes not in sunlight look very shadowed indeed. My shadowed clothes still have certain spots a lot brighter than the rest.

At least I figured out why the ENB couldn't produce pure blacks: Its enbpalette.bmp didn't have black along the left edge. Shrug.

Try version 0.301, it should help. Use ***Curve*** parameters set to 0 to make color of something to be 1. Or set COlorFilterAmount=1.0 if it's available. But you need to use weather system for that and built the table of similar weathers in _weatherlist.ini
